FIELD: dentistry.
SUBSTANCE: invention relates to a dental bleaching composition. Described is a tooth whitening composition comprising a hydrophobic copolymer, where the hydrophobic copolymer is a film-forming hydrophobic copolymer containing copolymer of 2-methylpropyl ester of 2-methyl-2-propenoic acid, polymer of 2-propenoic acid and N-(1,1,3,3-tetramethylbutyl)-2-propenamide, hydrophilic bleaching agent, where hydrophilic bleaching agent contains 35 % hydrogen peroxide, and polar solvent, where the polar solvent includes ethanol, and where the hydrophobic copolymer is present in amount of 0.1 to 60 % by weight relative to the total weight of the composition, where 35 % hydrogen peroxide is present in amount of 0.3 to 12 % by weight relative to total weight of composition.
EFFECT: technical result is creation of improved compositions for teeth whitening, characterized by excellent film-forming properties of bleaching agent.
